Four well-placed crosslinked UHMPWE acetabular liners of distinct design were retrieved subsequent to fracture failure of the rim. In each case, electron microscopy of the fracture surface revealed fatigue initiation markings associated with a stress concentrating...

Aseptic loosening attributed to cement fracture and the subsequent disruption of fixation interfaces remains a major long-term failure mode of cemented arthroplasty. Knowledge of the fracture strength of bone cement, especially in fatigue, is an important indicator of...

The enduring success of the low-friction arthroplasty first advanced by Sir John Charnley as a solution for severe hip arthritic problems may be appreciated from the fact that in 2003 more than 800,000 hip and knee arthroplasties were performed in the United States....

The enduring success of the low-friction arthroplasty first advanced by Sir John Charnley as a solution for severe hip arthritic problems may be appreciated from the fact that in 2001 more than 600,000 hip and knee arthroplasties were performed in the United States....
